The boy had been missing since May 3, when two men armed with handguns burst into his family's home and tied him up -- along with his mother and four siblings.

The men ransacked the home before leaving with Briant, a small amount of cash and some personal property, San Bernardino sheriff's spokeswoman Cindy Beavers said.

Authorities had not caught the suspects as of Saturday evening. Hoops said authorities have information about at least two suspects -- who were captured on video at a home-improvement store near the Rodriguez home buying tape like the kind that was used to bind the family.

He said the names of the suspects, and what authorities believe was a motive, are not being released because they could jeopardize the investigation.

He also declined to say what relationship the suspects may have had with the family or whether the kidnapping is linked with drug crime that has run rampant in Mexican border towns in recent months.

Members of drug cartels in the border region have been known to use kidnapping as a means of quick cash.

"If you take a look at the case, I'll let you do your own homework on it," Hoops told reporters.

Authorities from San Bernardino flew to Mexico late Friday to get Briant. Hoops said he appears to be in good health. His hair, which is shoulder-length in photographs that authorities had released, had apparently been shaved, Hoops said.

Hoops said Briant's mother is "a Mexican citizen living here in the United States," but that he is unsure of her immigration status. He said Briant was born in the United States.

Sgt. Doug Hubbard, who was in Calexico when Briant and his mother were reunited, called the meeting emotional.

"Tears even came to Briant's eyes," he said. "It was a beautiful thing."
